About our ductwork cleaning in Warner Estate
Every duct has its own route. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route and finds every access point before we quote. If you have ductwork that has never been cleaned and high readings at a recent grease test, we can help, from multi-storey ducts, horizontal duct runs and vertical risers onwards.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. In Warner Estate, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

When to call us in Warner Estate
A greasy duct is a fire path, in Warner Estate as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
What we are most often called out for:
- Fat dripping from the ductwork
- Thick deposits at the bottom of a vertical duct
- A rancid smell from the extract duct
- Gaps where access panels were never fitted
Term dates shape school work: for a school like The Winns Primary School, an extract clean fits neatly into a half-term or summer break.

Why it’s worth doing now in Warner Estate
There’s no law that names TR19. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, including the grease inside the extract ductwork. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.

What affects the cost of ductwork cleaning
Your quote is based on your site. We take into account:
- Whether we need access equipment or extra panels
- The times the site is available
- One-off work versus a regular cycle
- Travel, parking and unloading
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before work begins.
What to send for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Wide photos of the system and the area around it
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
How the job changes from site to site
Attenuators and discharge
At the end of the duct is the discharge. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Horizontal duct runs
A long flat run cannot be cleaned from one end. Any stretch out of reach is noted and can fit extra panels.
For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
The process
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes a shift or more, depending on the length of the runs and the number of access points. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Warner Estate.
- Diagnosis: a survey of the duct’s route, size and access.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- Bends, risers and the base of each riser get extra attention.
- The duct is signed off with readings, photos and a next clean date.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Clear the space around the work

Advice
Your questions about ductwork cleaning in Warner Estate
Do you do school kitchen extract cleaning in Warner Estate in the summer holidays?
Yes, and it’s the easiest time to do it. With about 27 schools and colleges on the FSA’s register within roughly a mile and a half of Warner Estate, it pays to plan holiday dates ahead. You can ring 0345 646 2711 or send us an email with the dates the site is empty.
Who enforces fire safety at workplaces in Warner Estate?
Fire safety enforcement in Warner Estate is handled by London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
How much does ductwork cleaning cost in Warner Estate?
It depends on the site, so we quote each one individually. To get one, give us a ring on 0345 646 2711 or use the quote form with the site type, opening hours and a few pictures.
How often does extract ductwork need cleaning?
The minimum depends on how long the kitchen cooks each day: 3-monthly for heavy use, 6-monthly for moderate and 12-monthly for light use. Grease readings may show it needs doing sooner.
How can I tell if my extract ducts are dirty?
We measure it. Readings are taken by Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). A mean above 200 microns, or 500 microns at any point, means it’s due.
Do you install duct access panels?
Yes, as part of our fits and repairs work. Panels go where they give the best access to sections that couldn’t be reached, and we’ll recommend where.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Ductwork cleaning in Warner Estate: the local picture
The FSA’s data shows about 32 pubs and bars registered within 1.5 miles or so of the middle of Warner Estate. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Warner Estate is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In Warner Estate, food businesses are inspected by environmental health officers from Waltham Forest council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.
A hospital like Wanstead Hospital, about 2.3 miles east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. A hall kitchen that only cooks for events, whether near St John's or elsewhere in Warner Estate, still needs its extract cleaned, just less often.
